Combination of photonic methods for quality assurance of high-integrity lightweight components made of CFK

Project information:

  • Project title: Combination of photonic methods for quality assurance of high-integrity lightweight components made of CFK
  • Acronym: KombiPhoton (Kombination photonischer Methoden zur Qualitätssicherung hochintegraler Leichtbaukomponenten aus CFK)
  • Duration: 36 months (start 01.05.2021)
  • Funding: FFG-PdZ / FTI-Initiative Produktion der Zukunft (RTI-Initiative Production of the Future)
  • Project partners:

    • FACC Operations Gmbh
    • FH OÖ Forschungs & Entwicklungs Gmbh

Goals:

The central objective of this research project is to research and develop a fast non-contact, inline-capable and therefore non-destructive testing system. In the future, this should enable 100% testing of highly integral, complex-formed lightweight components made of thermoplastic fiber composites, which offer significant advantages in terms of material consumption, design freedom and recyclability. The innovations planned for this purpose are, on the one hand, a thermography system with the ability to analyze complexly contoured surfaces and, on the other hand, a miniaturized laser-ultrasound system to examine difficult-to-access, critical interior areas. Combined data analysis and imaging will additionally enable and improve the defect detection limit and the identification of indications. The planned inspection system shall be suitable for and tested on a relevant and challenging use case from the aerospace industry.

  • Development of a 3D IRT measurement system and reconstruction method for complex shaped geometries
  • Development of a miniaturized scanning laser ultrasonic sensor
  • Multimodal tomography by image registration of LUS and IRT reconstruction data
  • Multiscale inspection for evaluation of unclear IRT indications by a local LUS measurement (region-of-interest technique)
  • Multiphysical identification of a defect by thermal (IRT) and elastic (LUS) waves and fusion of reconstruction data
  • Reduction of metrology costs by using new LUS detectors
